In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Chemists at University College London have shown how two of biology's most fundamental ingredients, RNA (ribonucleic acid) and amino acids, could have spontaneously joined together at the origin of ...

Many writers grouse when an editor makes a change in a story, but the consequences of changing a single word usually aren’t that dire. Not so with genetic instructions for making proteins. Even a ...

Researchers have developed a powerful tool capable of scanning thousands of biological samples to detect transfer ribonucleic acid (tRNA) modifications—tiny chemical changes to RNA molecules that help ...
